Abstract

The evolution of Chemical Engineering imposes a unique challenge to the design of

adequate modules in the laboratories. In this article we present a novel experimental module that

we have designed and are currently implementing in the Chemical Engineering laboratory. The

module includes topics of colloids, complex fluids and biotechnology, while also giving more

emphasis to molecular interactions. The final objective of the long-term project is the extraction

of lysozyme from egg white using Aqueous Bi-Phasic Systems. The project is divided between

engineering teams in three phases: bench-scale experiments, the unit operation and the final

extraction and scale-up calculations. Our focus is to implement a module that mimics the

continuity of real engineering projects through the use of a sequence of sub-projects that are

assigned to different groups in the class. The design of the long-term project forces students to

deal with the various degrees of uncertainty that are associated with realistic open-ended

problems. The approach is intended to provide a platform to teach and evaluate for an additional

set of “soft” skills. These important skills include leadership, composure under uncertainty,

critical thinking, creativity, group work, task division, time management, literature searches and

forward thinking. We believe that the introduction of high degrees of uncertainty into the

laboratory serves as a tool to prepare the students for a rapidly changing industrial world.

Introduction

The evolution of Chemical Engineering historically has been driven by changing

industrial needs and by research developments in a broad spectrum of areas. Some of the

relatively young areas of Chemical Engineering include semiconductors and microelectronics, [1-3] nanotechnology, chemical product design, and biotechnology. As a result, Chemical

Engineering educators are continuously challenged to identify and teach a changing set of skills
